There were 7 roses in the vase. Melanie cut some more roses from her flower garden. There are now 12 roses in the vase. How many roses did she cut?

hi <3

just subtract the two values

12-7 = 5

she cut 5 roses.

hope this helps :)

5

Step-by-step explanation:

12-7=5 so so she cut 5 from her garden.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
